Where has been your most effective placement for an aftermarket fuse?


Not looking for a debate with anybody on whether aftermarket fuses work or not, this thread is for those fortunate members with the hearing to know that they do indeed work.
I am very interested in your thoughts and opinions as to where they work the best, the biggest bang for your buck if you like.
For myself I am going to say it is in my Metrum Onyx DAC.
And not just my present DAC, all of my last 3 DAC,s showed a very nice easily audible improvement with an aftermarket fuse.
Next I would say is in my Gold Note phono stage and lastly in my BAT integrated amp.

So what or where would you say has been the most noticeable piece of equipment that has benefited from a fuse change in your system?
128x128uberwaltz
Has anyone using 6 of these wonder fuses in series?
Surely the improvement will be 6x as big?
At a cost of only $3,000 it's a snip.
@clearthinker -     Your improvement conjecture could potentially prove true, but- Math is not your forte.
Thanks rodman.
My math is well up to snuff.
No point in messing around with cheap uber-fuses.  The best cost $500 a pop, so six would be $3,000.

No doubt it is possible to engineer a fuse that would retail at $1,000 but only millercarbon would buy them.  I would be interested to know what is the maximum miller will pay for a wholly passive component; fuse or power cable.  And the max he would recommend a very rich audiophile to pay, money no object.

And to be honest I am really not that interested in that at all.
Thanks and stay safe.
To those with SMc Audio gear, Steve and Patrick seem to have done extensive fuse auditions during their equipment burn-in processes and do provide different recommendations for different gear and even recommendations to shade the presentation differently for the sonic preferences of different clients.  They did indeed recommend Furutech fuses when they built my preamp some years ago but I just received my amplifiers back from them early this year and at that time they offered me the choice between either SR Blue or Orange fuses.
